Metastasis is a process in which cancer cells spread from the original tumor site to other parts of the body. When cancer metastasizes, cancer cells travel through the bloodstream or lymphatic system and form new tumors in different areas.
This can occur even after the original tumor has been treated or removed. Metastasis can affect distant organs and make cancer treatment more challenging.
It is important to detect and treat metastasis as soon as possible to improve the chances of treatment success.
